Help Me Choose: Built-in Battery


Dell laptop batteries are designed to let you get the most from your PC, so when you're out on the road, working in the field, flying across country for business or just sitting in the coffee shop, you can go longer on a single charge of your battery. Power-intensive applications such as movies, streaming media, gaming and high-end software will cause your battery to drain more quickly than basic applications.

Dell new XPS™ laptops and Z-series laptop batteries are built in to the laptop and are not replaceable by the customer. Fewer parting lines and compartments reflect another element of craftsmanship that XPS is known for. The built-in batteries of these laptops are also much thinner than a standard laptop battery, enabling a significantly thinner system compared to those with a standard battery.

The Dell XPS laptops feature a battery gauge seamlessly integrated into the system, with a system power management gauge that lets you know how much power you are consuming, so you can better manage your tasks for optimum battery life.

Additionally, Dell XPS laptops offer a number of energy-saving features to help you conserve power, so you can work and play longer than ever.

Dell power management features include:
  • After two minutes idle, the XPS screen will dim
  • After 5 minutes idle, the XPS screen will switch off
  • After 15 minutes idle, the XPS system will go to sleep
  • An ambient light sensor adjusts the keyboard
  • Brightness based on environmental lighting

Battery life is how long your battery will last between charges. Battery pack lifecycle is how often a battery can be recharged before its charge capacity starts to degrade (for example, when a fully charged battery is reduced to 60 percent of the original battery charge capacity). This reduction of charge capacity in turn leads to a significantly reduced battery life. The reduction in charge capacity is normal on all rechargeable batteries.

Extending battery life
The easiest way to get the best battery life out of your Dell™ laptop is to select one of the pre-configured power plans, like power saver, or balanced by right clicking on the battery symbol in the bottom right corner (aka system tray). The pre-configured power plans automatically adjust key settings that can have a significant impact on battery life, like reducing screen brightness or dimming the display when you are not actively using your laptop.


For those who need to extend battery life as long a possible there are a few additional steps you can take that will help extend battery life, like:
• Turn off wireless — The F2 key is the quickest way to toggle wireless on and off. If you don’t need to be connected, then turning off wireless will help extend battery life.
• Limit workload — If you limit the number or applications you have running or the number of windows or tabs you have open, this can help extend battery life.
• Selective usage — Batteries will last a lot longer if you are reading emails and editing documents than if you are watching a movie or playing a video game.

Extending battery lifecycle
For select Inspiron™ laptops introduced in 2012, Dell has taken steps to extend the battery pack lifecycles of user replaceable and built-in battery packs. The Dell Inspiron R (3rd Gen), Inspiron R Special Edition and Inspiron Z laptops have battery packs designed to last up to 600 full discharge/re-charge cycles*. Purchasing a laptop with a 600-cycle battery pack may reduce the number of battery packs you need to purchase (and discard) and may help reduce your contribution of hazardous waste to landfills.

Desktop mode battery charge technology
Laptop owners can also take additional steps to extend a laptop battery pack lifecycle. For example, leaving your laptop plugged into AC power with the battery charged 100 percent all the time can actually contribute to accelerating the reduction of charge capacity and shorten the battery lifecycle.

Dell has also introduced a new battery charge setting, called desktop mode battery charge, that helps extend a laptop’s battery pack lifecycle. When enabled, desktop mode monitors the charge status of the laptop battery, and if it spends most of the time at 100 percent charge while connected to the power adapter, desktop mode will automatically adjust the charge levels of the battery. The adjustments include regularly allowing the battery to discharge, even while plugged in. The benefits are this helps slow the reduction of charge capacity over time, and may even decrease the need to purchase a replacement battery during the life of your laptop.


Note: If desktop mode is enabled, users will see battery charge vary between 50 percent to 100 percent while the power adapter is connected. To ensure batteries are charged to 100 percent, disconnect and reconnect the power adapter and the battery will charge to 100 percent.
